4-HYDROXYBUTYL ACRYLATE

4HBA, with a primary hydroxyl group at the end of a longer alkyl chain, gives excellent scratch resistance due to its high crosslinking ratio and unique flexibility

CAS No :2478-10-6 TSCA :2478-10-6 EINECS :219-606-3 ENCS :2-958

Features

·4HBA is the Acrylic ester which has a hydroxyl functional group and a double bond group in the molecule.

·Various vinyl monomers can be copolymerized with 4HBA.

·Polymers co-polymerized with 4HBA achieve a higher crosslinking ratio with curing agents .

Applications

·Paint and coating materials (excellent scratch resistance, mechanical properties, and acid rain resistance )

·Waterborne coatings.

·Powder coatings.

·UV/EB curable composition

·Adhesives

·Pressure sensitive adhesives
